New York Yankees first baseman Mark Teixeira will turn 33 on April 11, and he isn’t shy about admitting he has started his decline. Or admitting that he is overpaid.

In a candid interview with The Wall Street Journal, Teixeira acknowledges that age has taken a toll on his batting average (.308 in 2008, .251 in 2012) and that it is a trend that is unlikely to reverse course.

"This is my 11th year," Teixeira told the newspaper. "I'm not going to play 10 more years. I want 5 or 6 good ones. So that would say I'm on the backside of my career. And instead of trying to do things differently on the backside of my career, why not focus on the things I do well, and try to be very good at that?"

Teixeira still hits for power, though his 24 homers last season were his worst total of his 10-season major league career. As were his 123 games played. His 84 RBIs tied his career low, set in his rookie season.

The first baseman still has four years and $90 million remaining on his contract, and he understands that some fans will question his production in the coming seasons.

"I have no problem with anybody in New York, any fan, saying you're overpaid. Because I am," Teixeira told The Wall Street Journal. "We all are."

Added Teixeira: "Agents are probably going to hate me for saying it. You're not very valuable when you're making $20 million. When you're Mike Trout, making the minimum, you are crazy valuable. My first six years, before I was a free agent, I was very valuable. But there's nothing you can do that can justify a $20 million contract."
